This LPIC-1 practice question tests your understanding of devices, filesystems and fhs. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician runs 'blkid' and sees output like '/dev/sda2: UUID="abc-def-ghi" TYPE="ext4"'. Which command can mount this partition using its UUID?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
mount -U "abc-def-ghi" /mnt
mount -U mounts by UUID.
mount -I "abc-def-ghi" /mnt
Why wrong: -I is not a valid mount option.
mount /dev/sda2 /mnt
Why wrong: This mounts by device name, which may change.
mount -L "abc-def-ghi" /mnt
Why wrong: -L is for label, not UUID.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
mount -U "abc-def-ghi" /mnt
Option A is correct because the 'mount' command supports the '-U' option to specify a partition by its UUID, which is a unique identifier for the filesystem. This allows mounting without relying on device names like /dev/sda2, which can change across reboots. The UUID is taken directly from the 'blkid' output.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
mount -U "abc-def-ghi" /mnt
Why this is correct
mount -U mounts by UUID.
Clue confirmation
The clue word "which command" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
mount -I "abc-def-ghi" /mnt
Why it's wrong here
-I is not a valid mount option.
mount /dev/sda2 /mnt
Why it's wrong here
This mounts by device name, which may change.
mount -L "abc-def-ghi" /mnt
Why it's wrong here
-L is for label, not UUID.
Common exam traps
The trap here is that candidates may confuse the '-U' (UUID) option with the '-L' (label) option, or assume that any option that accepts a string can mount by UUID, leading them to select the incorrect '-L' or '-I' flags.
Detailed technical explanation
The UUID (Universally Unique Identifier) is a 128-bit value stored in the filesystem superblock, generated at creation time, and remains constant even if the device is moved to a different port or system. The 'mount -U' option reads the UUID from the kernel's device mapper or directly from the block device, ensuring reliable identification. In real-world scenarios, using UUIDs in /etc/fstab prevents boot failures when disk order changes (e.g., after adding or removing drives).
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the LPIC-1 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
